UNITED STATES PATENT OFFICE.

WILLIAM ROBERTSON, OF CHARLESTON, ILLINOIS.

BOW-STITCH CUTTER.

SPECIFICATION forming part of Letters Patent No. 557,887, dated April 7, 18 96.

Application led June Z2, 1895.

To LZZ whom, it may concer-n:

Beit known that I, VILLIAM ROBERTSON, a citizen of the United States, residing at Charleston, in the county of Coles and State of Illinois, have invented certain new and useful Improvements in Tools for Cutting the Bow-Stitches of Boots and Shoes, of which the following is a full, clear, and exact specification.

My invention relates to tools for the use of cobblers for cutting the bows of the stitches which secure the sole to the welt, so that the sole can be readily removed for half-soling, carrying with it the cut stitches. In the ordinary manner of cutting the stitches and removing the sole an ordinary shoemakers knife is run between the sole and welt. In this manner the stitches will be cut 5 but they will remain in the welt, so that they will have to be subsequently removed by an awl or other instrument.

The object of my invention is to provide an improved instrument by means of which the bows of the stitches may be readily out, so that as the sole is removed the threads will be drawn out of the Welt.

The invention consists in the novel construction hereinafter fully described and claimed.

In the accompanying drawings, Figure lis a perspective view of a stitch-cutting instrument constructed in accordance with my invention. Fig. 2 is a similar view showing the instrument in a dierent position.

In the said drawings the reference-numeral Serial No. 553,771. (No model.)

l designates a curved metal shank, one end of which is secured to a handle 2. The other end of this shank is beveled, as shown at E, bent at an angle, and formed with a groove B, having a point A at one side and a straight portion C at the opposite side. By reason of the end of the shank being beveled the points A and O will project beyond the concave cutting edge D, formed by the groove B.

In practice the instrument is inserted between the welt and upper, the portion C contact-in g with the Welt and the point A with the upper. The instrument is now pushed forward, when the cutting edge Will cut the bows of the stitches, the parts C and A preventing injury to the welt and upper, as said parts A and C project beyond and in front of the concave cutting edge D. After the stitches have thus been cut the sole may be removed, carrying with it the cut threads from the Welt.

Having thus fully described my invention, what I claim is- As an improved article a thread-cutter for boots and shoes, comprising the shank having its outer end bent at an angle and the extremity beveled, and formed with a concave groove forming a concave cutting edge and the welt and upper protecting portions at opposite sides of said groove and projecting beyond the concave cutting edge, substantially as described.

WILLIAM ROBERTSON.
